This RSA Generator, Encrypt and Decrypt tool is designed for IT professionals, students, and educators who want to explore public-key cryptography in a hands-on, customizable environment. You can generate RSA key pairs using your own passphrase, select key sizes (with 2048-bit recommended for general use), and choose how your private key is encrypted—using industry standards like 3DES under the PKCS#8 format. The tool also supports hybrid encryption workflows by letting you define the AES cipher mode and padding scheme, which are used when encrypting larger messages alongside the RSA keys.
Once you configure your settings, you can switch between the tabs to generate keys, encrypt, or decrypt data. This helps you understand the layered process of encryption—how symmetric and asymmetric encryption can work together in secure systems.
All cryptographic operations are handled server-side, but we want to assure you that we do not store, log, or retain any of your inputs or generated keys. However, we strongly discourage users from submitting production-grade secrets, real private keys, or sensitive personal data. This tool is intended for learning, experimentation, and testing purposes. Use it to deepen your understanding of encryption concepts—but always use vetted libraries and hardened environments when working with real-world security and cryptographic implementations.
